Description

A kind of tank for excrement pan water intaking valve

The utility model is a kind of inlet valve mechanism of automatic control toilet cistern water level.Especially the tank for excrement pan water intaking valve of forming by commutation plug, commutation body, lever, release handle, floating drum, tank, pressuring plate etc.

At present, the tank for excrement pan water intaking valve of selling on the market mainly contains float-ball type, float-type, hydraulic type three major types type.Now doing one with regard to above-mentioned series products analyzes: float-ball type, and use amount maximum a kind of promptly adopts the ball float of the about 12cm of diameter, utilize water level to rise, hold up ball float, rotate by the balance pivot that connects on the ball float and oppress water inlet, reach the purpose of closing import water, this series products is especially big because of the ball float, the volume that adopt, can not be general, and lever is long, adopt the shape of changing, now in use product also is most early with malfunctioning, causes the very big waste at water source.Float-type: hold up floating drum by the water level rising, lifting interlock small lever control one cover of floating drum is carried out the supercharging device of closing water inlet by pressure principle, and its weak point is floating drum volume big (about Φ 90mm), and supercharging device stops up easily, the come-up tube edge comes discharge hour, and is out of control easily.Hydraulic type: with reference to external product production, the malfunctioning reason of its product maximum is that the booster cavity water inlet stops up, cause whole functional malfunctioning, secondly steam vent when mounted, unimpeded to guarantee exhaust, in case exhaust is blocked, water inlet just can't be closed, this type of water intaking valve, recently national departments concerned also must not notify and is produced.

The purpose of this utility model is the shortcoming that overcomes above-mentioned prior art, provide a kind of applied hydraulic pressure scope big, do not have stop up, water intake velocity is fast, noiseless, regulating water level are convenient directly perceived, the tank for excrement pan water intaking valve that profile is small and exquisite.

The technical solution of the utility model is summarized as follows:

The top inner chamber of tank for excrement pan water intaking valve main body of the present utility model (12) is provided with skin valve (7), spring (21), pressuring plate (11).Skin valve (7) be arranged on valve port (9) above, pressuring plate (11) is carried out and is covered on boost port (23), and adds upper spring (21), its objective is not have to appoint the water source size that comes from water inlet (27), through stopping of pressuring plate (11), must satisfy the water yield that enters aperture (10) earlier.Prepass (5), back passage (6), commutation body (3), commutation plug (1), sealing mat (4), relief hole (1) formation reversal valve device have been provided with on valve body (12) top, connect commutation plug (1) by lever (16) and reach commutation plug (1) moving up and down in commutation body (3) through the rotation of fulcrum (2), when commutation plug (1) moves upward, drive sealing mat (4) sealing relief hole (17), skin valve (7) supercharging, shut valve port (9), when commutation plug (1) moves downward, open relief hole (17), skin valve (7) decompression.Go up fixedly outlet pipe (20) at valve body (12), extend delivery port (26) to the lower edge, upwards take over control siphon hole (19), after skin valve (7) decompression was risen, the water that is flowed out by valve port (9) flowed into water tank through outlet pipe (20) delivery port (26).When because of pipeline water source pressure is not enough, when water inlet (27) is adopted living negative pressure, mend air by anti-siphon hole (19), take advantage of water to blow back into tube edge with caisson through delivery port (26).Pass lever (16) hole by release handle (15) and connect adjusting screw(rod) (18), adjusting screw(rod) (18) is top in the floating drum that is threaded (25), floating drum (25) is gone up fixedly tank (24), by the rotation of release handle (15), adjusting screw(rod) (18), set the high and low position of floating drum (25) and tank (24).

The utility model is further described with embodiment below in conjunction with accompanying drawing 1, accompanying drawing 2.

Accompanying drawing 1 is the sectional drawing that the utility model embodiment valve port is opening.

Accompanying drawing 2 is sectional views that the utility model embodiment valve port is closed condition.

Tank for excrement pan water intaking valve of the present utility model shown in accompanying drawing 1, accompanying drawing 2,

One can be installed on water tank, and the water intaking valve valve body (12) of other mechanism also can be installed in the connecting pipe water source, at the top inner chamber of valve body (12), the skin valve (7) of unlatching effect has been installed, and plays pressuring plate (11), the spring (21) of pressurization.Top in valve body (12) is by commutation plug (1), commutation body (3), relief hole (17), sealing mat (4), the changement that prepass (5), back passage (6) are formed.Form the water level induction mechanism by pivot pin (2) lever (16), release handle (15), adjusting screw(rod) (18), floating drum (25), tank (24).With water tank the sealing ring (13) seal is installed, the installation nut (14) etc. that works the effect of installing and fixing has constituted this inlet valve mechanism.

Now be described in detail with regard to each mechanism's actual working state: the water as certain pressure enters valve inner by inlet opening (27), at first running into pressuring plate (11) stops, be divided into two the tunnel, one road water preferentially enters aperture (10) and advanced that screen pack (8) filters the prepass (5) of flowing through, relief hole (17) enters water tank, therefore the time, water tank is anhydrous, the weight of water reception tank (24) and floating drum (25) adjusting screw(rod) (18) be in down position from heavy work lever (16), commutation plug (1), relief hole (17) is in opening.Another road water effect pressuring plate (11), compression spring (21) leaves the neutral of boost port (23) between banking stop (22) and enters valve port (9), backs down flow through outlet pipe (20), delivery port (26) of skin valve (7) and enters water tank, reaches the water intaking valve purpose of opening.Continuous rising along with water level, suitable for reading near tank (24), water in the tank (24) with water tank be tending towards one to, inside and outside lump together, tank (24) loses weight, the floating drum of Xiang Lianing (25) is because genus enclosed type suitable for reading simultaneously, inner air is adopted capture power, drive adjusting screw(rod) (18), lever (16) moves upward, because (16) one on lever pinned by pivot pin (2), so, lever (16) rotates counterclockwise along pivot pin (2), drive the commutation plug (1) that flexibly connects, sealing mat moves on (4), closes relief hole (7), like this, through aperture (10), the water of prepass (5) can only through after passage (6) enter skin valve (7) the inside, utilize pressure principle, skin valve (7) begins to splash and rises, sealing valve port (9), like this, relief hole (7), the water that valve port (9) flows is blocked, and pressuring plate (11) is pressed boost port (23) in the effect lower seal of spring (21), finishes the purpose that water intaking valve is closed.

The utility model has following advantage compared with prior art:

1. the commutation plug is partly adopted in control, and the tool auto-lock function, so under high-pressure water, Can not adopt living seepage, the incomplete phenomenon of water shutoff.

2. employing shunt structure only needs the flow through water of controlling organization of sub-fraction was carried out Filter, the service efficiency that has greatly prolonged screen pack.

3. owing to adopt shunt structure, valve port no longer includes filter mantle stops that valve port has been opened Entirely, reduce damping, water intake velocity is improved greatly, and noiseless.

4. because of commutation is plugged with self-lock ability, the floating drum size significantly reduces, and makes product design small and exquisite attractive in appearance, and it is convenient to regulate water level, is applicable to all size, and the shape water tank is installed.
